A system (40) for damping motion of a wind turbine (10a) is provided. The system (40) includes a sensor (42), a movable mass (44), an actuator (58), and a controller (46). The sensor (44) is operable to provide a signal representative of a motion of the wind turbine (10a) in one or more degree of freedoms. The movable mass (44) is associated with the actuator (58) and is disposed on a blade (24a) of the wind turbine (10a) and is configured for movement along a length of the blade. In response to the sensor (42), the controller (46) is operable to direct the actuator (58) to move the movable mass (48) along a length (50) of the blade (24) to a degree effective to dampen motion of the wind turbine (10a) in one or more degree of freedoms. |
